Which pair of the following chlorides do not impart colour to the flame?
Text Solution
Verified by ExpertsThe correct answer is:
B
Among the alkaline earth metals, the size of beryllium and magnesium metals is very small. Therefore, the electrons in these metals are bounded more strongly and are not excited by the energy of flame to higher energy states. Hence, these metals or their salts do not impart any colour to the flame.
